CENTRIFUGAL PUMPING MEcHANIsM.

Specification of Letters Patent. Patented Aug, 18,1914, Application meaFebruary 1e, 1912. serial No. 677,894.

To all whom t may concern Be it known that I,MARv1N B. VAN Ness,residing at Welsh, in the parish of Calcay sieu and State of- Louisiana,have invented certain new and useful Improvements in Centrifugal'PumpingMechanism, of which the following is a specification.

, My invention relates to certain new and useful improvements incentrifugal pumping mechanism for wells, and the invention has for oneof its objects to provide means for strengthening the connection betweenthe drivingpulley and the line shaft, whereby the pull of theldrivingbelt will not buckle the line shaft. y

Another object of the invention is to provide means whereby the lineshaft and the shaft` casin with its bearings may be'pulled under straininto perfect alinement to pre- -vent undue 5friction in the bearings dueto and arrangement of parts, all of which will be rst fullydescribed,and then be speciically' pointed out in the appended claims, referencebeing had tof the accompanying drawings, .in which Figure 1, is acentral longitudinal vvertical section o'f the upper part of the pumpingmechanism; Fig. 2, isa vi'ew similar to Fig.

' 1 of the lower part of the mechanism, showing the pump and the'suction pipe with the sealing mechanism that coperates with the suctionpipe. Fig. 3 isa cross section on the line 3 3 of Fig. 1. Fig. 4 is acrosssection on the line 4 4 of Fig. 1. Fig. 5 is a detail .section onthe line 5-.5 of Fig. 2.

In the drawings in 'which'lilae numerals and letters of referenceindicate like parts in all of the figures, 1 is the pit Ior well casing,which .may be of the ordinary construction, and which, at the topreceives' the pit top 2.

3 is the pump'head which is securedto the pit top 2, as at 4l, the pumphead 3 having an internal thread 5' at` its lowerend to re, ceive thewater pipe 6. The pipe 6 may be made either in a single length or insections )oined together asI at 7, depending onk the sary by therequirements of the particular well in which the mechanism is to beemployed. l

9 is the outlet pipe for the wat'er which is joined at 10 over thedischarge opening 8, of the pump head 3.

15 designates the pump casing which in the present form of the inventionis of the duplex type and has its ends closed by the 'caps 13 and 16,which are secured at 14 and 17, respectively to the casing 15. To Atheupper cap 13, the uniony 11 that receives the lower end of the waterpipe 6, is fastened as at 12 so as to bring the pipe 6 in connectionwith the interior of the casing 15. The suction pipe 19 is connected tothe casin '15 through the medium of the union 18. he pump casing 15incloses the partitions which carry the shaft bearings 20 and 21respectively, and also inclose the impellers 23.

The construction ofthe Apump e. the parts which include the casing 15and its`internal parts) may be of any approved construction, as the sameper se forms no part of the present invention.

24 is the lower thrust bearing which is secured tothe shaft 22, it beingof course understood that when the Water pipe 6, and the shaft casing44, are made in sections, the shaft 22 would also be made in sections,

coupled together by a sleeve 25, as is the. 'usual practice. The shaft'22, at its upper end, has a feather slot or groove 26 in` which the keyor feather 36 of the driving pulley 35 lies, and with which the setscrew 29 of the adjusting nut 28 coperates. The ad- .60 depth of thewell, and as may be made necesjusting nut 28 has each facetapped at 30to receive the set screw 29,whereby minute adjustments may be made, andthe set screw always enters into the groove 26 to assure non-slipping ofthe adjusting nut, it being understood. of course that the upper end ofthe shaft 22 will be threaded as at 27 to receive the nut 28.

31-is the main bearing member. that fits on the pump head 3 and supportsthe line shaft 22 and .the im ellers 23; The bearingy 31 is pocketed andushed 'with bearing metal as lat 33 to receive the long .hub 34 of thepul- 3? ie the upper ball race member that turns with the head. 34 andbetween which for the shaft 22. lBelow the web 39 of the bearing member31, the said member is counter-bored as at 41 and tapped as at 42 toreceive the upper end of the shaft casing 44 which is threaded at 43 tocoperate with the threads 42.v j i The shaft casing consists of aplurality of tubes 44 which are joined to bearings 45 by collars 46, thecollars 46 being spaced apart to retain the spider 47 which is swivellymounted on the bearing 45 and rests snugly in .(but is not secured to)the inside of the water pipe 6. The bearing members 45 have upwardlyprojecting sleev'es 48 to form pockets 49 to collect anymsediment thatmay accumulate in the pipe 44 and prevent it working into the bearingface of the res ective bearing member 45. The lowers aft case section 44is secured to the upper bearing member 21 of the pump at 56 through themedium of a reducing joint 57, as best indicated in Fig. 2 of thedrawings.

The bearing member 31 has a water chamber 32 that is provided with aninlet 50 and al water outlet 51 whereby the water of the well maycirculate around the bearing proper of the bearing member `31 and keep'the same cool. Thebearing member 31 may also be provided with an oilduct 52 into which oil may be conveyed from a suitable reservoir, notshown, through a pipe 53, if desired.

58 designates the strainer pipe into .which the suction pipe 19,projects.

60 is the seal which effects a snug joint between the pipes 19 and 58,and the seal 60 is in the nature of a collar,` which slides on a pipe19, and has its lower face coniformed to project into the pipe' 58. lnorder to assist in forming a tight seal and also to support the strainerpipe, it may be provided at its upper end with a collar 59 having lugs62 to enter bayonet slots 65, in the body 64 of the pit bottom member63, as best shown in Fig. 2 of the drawings.

ln putting the pump in the well, the well pit is of course first placedinto position, and the strainer pipe likewise. The pump casing and itscarried parts, the suction pipe 19, the water pipe 6, the line shaft andthe shaft casing are all assembled together with the pum head yand 'pittop before being lowered into the well. After they are lowered into thewell, the bearing member 31 is put into place and screwed to 'the upperpipe section 44. By applying a pipe wrench to the bearing member 31 andturning it, tension can be put on the shaft casing 44 to draw it intoabsolutely' true alinement and thereby aline all of the bearings 45 (thenumber of which-will depend on the depth of the well) so that the shaft22 will not bind in the said bearings. After the required tension hasbeen applied to the casing 44, the bearing member 31 is bolted down bythe bolts 55 to the pump head. The. pulley 35 is slipped into place andthe impellers 23 properly adjusted bythe nut 28. The pump is then readyfor operation, it being understood of course that the seal 60 is held onthe pipe, and when the said pipel is lowered into place, it effectivelyseals the connection between the suction pipe 19 and the strainer pipe58.

ln operation, power is applied to the pulley 35 to turn the shaft 22,thereby setting the impellers 23 into operation, to suol; the water upthe pipe 19, pass it through the pump `casing 15 and force it upwardlythrough the waterpipe 6 in the duct formed between such pipe and shafteasing 44, out through the outlet 9. rlhe water comes in practicallydirect contact with the bearings 45 and'collars 46 and thus insures theproper cooling of the bearings 45, while the water in the chamber 32will insure proper cooling of the hearing 33 at all times.

From the foregoing, it will be observed, by my present construction, amore etlicient pump is contained than heretofore, and the parts are socombined and designed that with a minimum effort in the assembling ofthe parts, and at any other time when necessary, absolute, alinement ofthe various bearings 45 can be had by simply tightening up theconnection between the upper section 44 of the shaft casing and thebearing member 31.

F rom the foregoing description taken in connection with theaccompanying drawings, it is believed the complete construction,operation, and'advantages, of the invention will be apparent to thoseskilled in the art to which it appertains.
